Description
Technical field
The present invention relates to charger for mobile phone field, specifically relate to mobile phone wireless charger.
Background technology
Present charger for mobile phone is all with long data wire, is placed in bag in disorder especially, seems loaded down with trivial details.When mobile phone is in charging process, when having incoming call, people often directly receive calls, and do not pull out charging wire, in communication process, because of electric appliance load, charger delivery efficiency increases, and temperature raises, now, if extended telephone conversation, the increase of charger load will be caused to cause controllable silicon to damage and cause electric leakage, give fatal risk.
Along with the development of wireless charging technology, the appearance of some new materials and the progress of technology, the efficiency overcoming wireless charging is to a certain extent low, and distance is extremely short, the factors such as poor stability.Wireless charging technology is that low power electric appliance charging provides conveniently.
Summary of the invention
What the present invention needed to solve is existing mobile phone wired charger without the troublesome problem of charging, provides a kind of mobile phone wireless charger.
The present invention solves the problem by the following technical programs:
Mobile phone wireless charger, comprises power supply transmitter module, power supply receiver module, Receiver Module and radiofrequency emitting module;
Power supply transmitter module is connected by electromagnetic wave with power supply receiver module; Power supply receiver module is connected with radiofrequency emitting module; Radiofrequency emitting module and Receiver Module wireless connections; Receiver Module is connected with power supply transmitter module; Radio communication between Receiver Module and radiofrequency emitting module realizes the intelligent control switch of wireless charger, makes charger Practical Intelligent more.
In such scheme, preferably power supply transmitter module comprises commercial power interface, switch, oscillator, power amplifier and transmitting coil; Commercial power interface input is electrically connected with city; The output of commercial power interface is connected with transmitting coil through switch, oscillator, power amplifier; The input control end of switch is connected with Receiver Module; Switch mainly realizes the Push And Release charged, and oscillator mainly realizes launching the adjustment of front power, and launching for electric energy provides firm power.
In such scheme, preferably power supply receiver module comprises receiving coil, filter, rectifier, charge controller and handset port, and receiving coil output is connected with charge controller through filter, rectifier; Charge controller is connected with handset port and radiofrequency emitting module.
In order to better can improve the accuracy of transmitting and reduce exploitation price, in such scheme, preferably Receiver Module and radiofrequency emitting module are RF radio-frequency module.
In such scheme, preferably described RF radio-frequency module uses control chip model to be RF2401, can meet the requirement of the charging distance of charger very well.
Advantage of the present invention and effect are:
1. by realizing the wireless transmission of electric energy between power supply transmitter module and power supply receiver module in electromagnetic mode, power supply receiver module can directly be inserted on mobile phone, can provide convenience to charging, solves the troublesome problem of charging of traditional wire charger.
2. use the radio communication between Receiver Module and radiofrequency emitting module to realize the intelligent control switch of wireless charger, when power supply receiver module inserts mobile phone, radiofrequency emitting module sends and informs Receiver Module, Receiver Module controls the switch of power supply transmitter module, makes charger Practical Intelligent more.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
Mobile phone wireless charger, comprises power supply transmitter module, power supply receiver module, Receiver Module, radiofrequency emitting module and housing, as shown in Figure 1.
Power supply transmitter module is connected by electromagnetic wave with power supply receiver module; Power supply transmitter module comprises commercial power interface, switch, oscillator, power amplifier and transmitting coil; Commercial power interface input is electrically connected with city; The output of commercial power interface is connected with transmitting coil through switch, oscillator, power amplifier; The input control end of switch is connected with Receiver Module; Transmitting coil is connected by electromagnetic wave with power supply receiver module; When power supply receiver module has mobile phone to insert, when switch can receive the control signal of Receiver Module, switch open, when mobile phone unplugs is, switch cuts out; Oscillator mainly realizes launching the adjustment of front power, launch for electric energy and firm power is provided, power amplifier realizes the power amplification before electric energy transmitting, make the distance of transmitting farther, strengthen the distance of wireless charging greatly, transmitting coil mainly realizes electric energy and converts electromagnetic wave to, and is gone out by electromagnetic radiation.
Power supply receiver module comprises receiving coil, filter, rectifier, charge controller and handset port, and receiving coil output is connected with charge controller through filter, rectifier; Charge controller is connected with handset port and radiofrequency emitting module; Receiving coil and transmitting coil are by electromagnetic wave wireless connections; Through wave filter filtering burr after receiving coil receives electromagnetic wave, by rectifier, analog signal is transferred to electric energy again, charging is controlled again by charge controller, handset port is the common at ordinary times handset port of mobile phone, be applicable to intelligent machine up to specification to use, when handset port inserts mobile phone, charge controller can sense that mobile phone inserts, and charge controller passes to radiofrequency emitting module control signal.
Receiver Module is connected with power supply transmitter module, Receiver Module and radiofrequency emitting module are RF radio-frequency module, RF radio-frequency module uses control chip model to be RF2401, wherein, Receiver Module and power supply transmitter module also can use WIFI module or bluetooth module, just use RF radio-frequency module price can be relatively low, easilier promote in society, mainly realize the effect of intelligent switch, provide charger more easily to people.
Below the preferred embodiment of the invention is illustrated, but the present invention is not limited to embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the invention spirit, and these equivalent modification or replacement are all included in the scope of the application.
